Beamng detected as a virus???

I woke up and turned on my pc to play Beamng, but when i pressed play steam said the executable of the game was lost. That's kinda weird... Then steam proceeds to reinstall the executable of the game. It reinstalls pretty fast so i try to start the game again. My antivirus immediately blocks and deletes the executable of the game because it thinks that it is a virus, and that's the reason it was deleted when i started my pc.
So, my question is ¿What's up with this? ¿Why is it detecting the ".exe" of the game as virus?

 

That's a common issue, a lot of anti-viruses are not playing nice with this update. It was addressed in the 0.19 Discussion thread
